Kombucha Makers Unite; Where to ask and be answered in Recipe Sharing Posted October 30, 2016 So I had my first kombucha explosion on Thursday night. Thankfully no one was in the room...it was around 10 at night and hubby and I heard a pop then glass tinkling. That took 45 minutes of cleaning before we could go to bed. What bottles do you guys use for your second ferment? I'm in the market (especially if they can be bought online...).
